问题
I have seen similar questions asked, but none have answered my question. I am relatively new to python, and have no idea what i'm doing.
回答1:
Use:
>>> bool(1)
True
>>> bool(0)
False
>>> int(bool(1))
1
>>> int(bool(0))
0
Can convert back too.
回答2:
Unless you don't want to explicitly use Boolean type variable you don't need to. Python accepts it as True in many expression:
print(True == 1)
print(False == 0)
Out:
True
True
In other cases you can use bool(1) of course.
print(bool(1))
print(bool(0))
Out:
True
False
回答3:
Only the following values will return False when passed as a parameter to bool()
- None
- False
- Zero of any numeric type. For example, 0, 0.0, 0j
- Empty sequence. For example, (), [], ''.
- Empty mapping. For example, {}
- objects of Classes which has bool() or len() method which returns 0 or False
Everything else returns True

Very simple:
bool(1)
Here are a few scenarios, to show:
print(bool(1))
Will return: True
print(bool(0))
Will return: False
